Arsenal goalkeeper Bernd Leno says they're stronger defensively under manager Mikel Arteta.

The Gunners claimed a 1-0 win over Manchester United on Sunday, a first win at Old Trafford since 2006.

Leno believes that the defensive side of the game is now much improved - noting that it is “more impressive" under Arteta than his predecessor.

He said, "First of all it was a very important win for us when you look at the table.

“It's been a long time since we won away against a team from the big six, and as well at Old Trafford. It's been 14 years I think, so too long but finally we've done the job.

“It was a very collective, strong performance from us.

"Our players were brilliant and I think everybody had the right attitude and mentality to win. It was very hard for Man United to create chances.

“At the end of the day, this is the key. The collective performance and defensive work were really important and I think we've worked on that.

“You can already see that it's much more impressive than it was one or two years ago."
